BJFU-218-基于链式存储结构的图书信息表的最贵图书的查找

如果编译不通过，可以将C该为C++

#include<stdio.h>
#include<stdlib.h>
#define MAX 100
//创建节点
typedef struct Book{
    double no;
    char name[MAX];
    double price;
    struct Book * next;
}Book,*BList;

//创建链表
void CreatList(BList &B,int n)
{
    B = (BList)malloc(sizeof(Book));
    B->next = NULL;
    BList rear = B;
    for(int i=1;i<=n;i++)
    {
       //这里用的是尾插法
       BList p = (BList)malloc(sizeof(Book));
       scanf("%lf",&p->no);
       scanf("%s",p->name);
       scanf("%lf",&p->price);
       if(p->no==0&&p->name[0]=='0'&&p->price==0) break;
       rear->next = p;
       p->next = NULL;
       rear = p;      
    }
}
//获得最贵图书的价格，并返回其值
double getCost(BList &B)
{
    BList p = B->next;
    double cost = p->price;
    int cout = 0;
    while(p)
    {
        if(p->price > cost)
        {
            cost = p->price;
        }
        p = p->next;
    }
    return cost;
}
void traverse(BList B,int n,double cost)
{
    BList p = B->next;
    int cout = 0;
    for(int i=1;i<=n;i++)
    {
        if(p->price==cost) cout++;     //计算最贵图书的个数
        p = p->next;
    }
    printf("%d

    BList q = B->next;
    for(int i=1;i<=n;i++)

        if(q->price==cost)           //如果图书的价格是cost，就输出

        }

    }


}
